加入其他表格 laravel 中不存在按结果分组？

Question

我有两个 table 和一个枢轴 table。结算table是这样的：

        $table->ulid();
        $table->string('track_id', 36);
        $table->string('payee_user_id', 36);
        $table->string('terminal_type', 36)->nullable();
        $table->string('terminal_provider', 36)->nullable();
        $table->string('terminal_psp', 36)->nullable();
        $table->string('terminal_id', 36)->nullable();
        $table->string('acceptor_id', 36)->nullable();
        $table->string('terminal_no', 36)->nullable();
        $table->string('account_bank_id', 36)->nullable();
        $table->string('account_id', 36)->nullable();
        $table->string('account_deposit', 36)->nullable();
        $table->string('account_iban', 36)->nullable();
        $table->integer('count')->nullable();
        $table->decimal('amount_settle', 15, 2);
        $table->decimal('amount_wage', 15, 2);
        $table->timestamps(6);

交易table是这个

        $table->ulid();
        $table->string('payee_user_id', 36);
        $table->string('type', 36);
        $table->string('terminal_id', 36);
        $table->string('terminal_no', 36);
        $table->string('terminal_type', 36);
        $table->string('acceptor_id', 36);
        $table->string('terminal_psp', 36);
        $table->string('terminal_provider', 36);
        $table->decimal('amount_settle', 15, 2);
        $table->decimal('amount_wage', 15, 2);
        $table->string('account_id', 36)->nullable();;
        $table->string('account_bank_id', 36)->nullable();;
        $table->string('account_deposit', 26)->nullable();
        $table->string('account_iban', 26)->nullable();
        $table->string('wallet_id', 36)->nullable();
        $table->timestamp('paid_at', 6);

settlements_transactions table是这样的：

        $table->string('transaction_id')->index();
        $table->string('settlement_id')->index();
        $table->foreign('transaction_id', 'fk_transaction_id')
            ->on('transactions')->references('id');

        $table->foreign('settlement_id', 'fk_settlement_id')
            ->on('settlements')->references('id');

我是在结算中插入交易的group by table如果我之前没有保存过

$transactions = DB::table('transactions')
        ->where('paid_at', '<', $date)
        ->where('terminal_type', Transaction::PRIVATE)
        ->where('terminal_provider', Transaction::SHAPARAK)
        ->distinct()->selectRaw(
            'account_iban,
             account_deposit,
             account_bank_id,
             payee_user_id,
             account_id,
             terminal_psp,
             terminal_id,
             terminal_no,
             acceptor_id,
             account_id,
             SUM(amount_settle) as amount_settle,
             SUM(amount_wage) as amount_wage,
             COUNT(id) as count'
        )->groupBy(
            'payee_user_id',
            'account_id',
            'account_iban',
            'terminal_psp',
            'terminal_no',
            'terminal_id',
            'acceptor_id',
            'account_id',
            'account_deposit',
            'account_bank_id',
        )->orderBy('payee_user_id')
         ->orderBy('account_id')
         ->orderBy('terminal_psp')
        ->orderBy('terminal_id')
        ->orderBy('account_id')
        ->orderBy('account_deposit')
        ->orderBy('account_bank_id')
        ->orderBy('account_iban')
        ->orderBy('terminal_no')
        ->orderBy('acceptor_id')
        ->get();

      foreach ($transactions as $transaction) {

        $exist = DB::table('settlements')
            ->where('payee_user_id', $transaction->payee_user_id)
            ->where('account_id', $transaction->account_id)
            ->where('account_deposit', $transaction->account_deposit)
            ->where('terminal_id', $transaction->terminal_id)
            ->where('terminal_psp', $transaction->terminal_psp)
            ->where('account_bank_id', $transaction->account_bank_id)
            ->where('terminal_provider', Transaction::SHAPARAK)
            ->where('terminal_type', Transaction::PRIVATE)
            ->where('settlements.created_at', '>=', Carbon::today())
            ->join('settlement_statuses', 'settlement_statuses.settlement_id', 'settlements.id')
            ->applySettlementLastStatusSubJoin('settlement_statuses')
            ->applySettlementLastAccepted('settlements')
            ->exists();

        if ($exist) {
            continue;
        }

      //insert in settlements table

   }

我不想检查循环中是否存在。如果结算中不存在，我需要按结果分组交易 table。

Answer 1

当您调整交易选择时，无需验证结算中是否已存在分录。原则是进行“左连接”，然后过滤在定居点中没有相应条目的值 table (->whereNull('s.id')).

此解决方案的问题可能是性能问题，具体取决于多种因素。无论如何，如果正确使用索引，这应该不是问题。


$transactions = DB::table('transactions AS t')
    ->leftJoin('settlements AS s', function ($join) {
        $join
            ->on('s.payee_user_id', '=', 't.payee_user_id')
            ->on('s.account_id', '=', 't.account_id')
            ->on('s.account_deposit', '=', 't.account_deposit')
            ->on('s.terminal_id', '=', 't.terminal_id')
            ->on('s.terminal_psp', '=', 't.terminal_psp')
            ->on('s.account_bank_id', '=', 't.account_bank_id')
            ->where('s.terminal_provider', '=', Transaction::SHAPARAK)
            ->where('s.terminal_type', '=', Transaction::PRIVATE)
            ->where('s.created_at', '>=', Carbon::today());
    })
    ->whereNull('s.id')
    ->where('t.paid_at', '<', $date)
    ->where('t.terminal_type', Transaction::PRIVATE)
    ->where('t.terminal_provider', Transaction::SHAPARAK)
    ->distinct()->selectRaw(
        't.account_iban,
             t.account_deposit,
             t.account_bank_id,
             t.payee_user_id,
             t.account_id,
             t.terminal_psp,
             t.terminal_id,
             t.terminal_no,
             t.acceptor_id,
             t.account_id,
             SUM(t.amount_settle) as amount_settle,
             SUM(t.amount_wage) as amount_wage,
             COUNT(t.id) as count'
    )->groupBy(
        't.payee_user_id',
        't.account_id',
        't.account_iban',
        't.terminal_psp',
        't.terminal_no',
        't.terminal_id',
        't.acceptor_id',
        't.account_id',
        't.account_deposit',
        't.account_bank_id',
    )->orderBy('t.payee_user_id')
    ->orderBy('t.account_id')
    ->orderBy('t.terminal_psp')
    ->orderBy('t.terminal_id')
    ->orderBy('t.account_id')
    ->orderBy('t.account_deposit')
    ->orderBy('t.account_bank_id')
    ->orderBy('t.account_iban')
    ->orderBy('t.terminal_no')
    ->orderBy('t.acceptor_id')
    ->get();

编辑：相同的解决方案，但关系 table usage..

<?php

$transactions = DB::table('transactions AS t')
    ->leftJoin('settlements_transactions AS st', function ($join) {
        $join
            ->on('st.transaction_id', '=', 't.id')
            // these "where" conditions are maybe redundant
            ->where('s.terminal_provider', '=', Transaction::SHAPARAK)
            ->where('s.terminal_type', '=', Transaction::PRIVATE)
            ->where('s.created_at', '>=', Carbon::today());
    })
    ->whereNull('st.transaction_id')
    ->where('t.paid_at', '<', $date)
    ->where('t.terminal_type', Transaction::PRIVATE)
    ->where('t.terminal_provider', Transaction::SHAPARAK)
    ->distinct()->selectRaw(
        't.account_iban,
             t.account_deposit,
             t.account_bank_id,
             t.payee_user_id,
             t.account_id,
             t.terminal_psp,
             t.terminal_id,
             t.terminal_no,
             t.acceptor_id,
             t.account_id,
             SUM(t.amount_settle) as amount_settle,
             SUM(t.amount_wage) as amount_wage,
             COUNT(t.id) as count'
    )->groupBy(
        't.payee_user_id',
        't.account_id',
        't.account_iban',
        't.terminal_psp',
        't.terminal_no',
        't.terminal_id',
        't.acceptor_id',
        't.account_id',
        't.account_deposit',
        't.account_bank_id',
    )->orderBy('t.payee_user_id')
    ->orderBy('t.account_id')
    ->orderBy('t.terminal_psp')
    ->orderBy('t.terminal_id')
    ->orderBy('t.account_id')
    ->orderBy('t.account_deposit')
    ->orderBy('t.account_bank_id')
    ->orderBy('t.account_iban')
    ->orderBy('t.terminal_no')
    ->orderBy('t.acceptor_id')
    ->get();

加入其他表格 laravel 中不存在按结果分组？

group by result not exist in join other tabel laravel?

mysql
